Rewarding users for downloading other games

I have multiple games on the iOS app store. I want to give users free game coins when they download any of my other games. Is there a way to do this without setting up a server? In case a server is the only option, what is the best way to do so!

Solution

  • Here's a useful link: Share data between two or more iPhone applications

    Basically, I believe the options are:

    1. Use UIPasteBoard as mentioned here. Sample code here.
    2. Use custom URL schemes
    3. Using keychain
    4. Using a server - the first time an app is opened it would send a request to the server to notify that the app was installed; the app offering credits would send a request (probably when it becomes active) to check if the user has downloaded any new apps.
